Offset Parameters for Uplink Control Information

ABSTRACT

A wireless device receives radio resource control message(s) indicating: first uplink resources, of an uplink data channel, for a periodic resource allocation; a first offset parameter for uplink control information (UCI) transmission via the periodic resource allocation; and a plurality of second offset parameters for UCI transmission via a dynamic grant. A first UCI is transmitted via a number of the first uplink resources. The number of the first uplink resources is determined based on the first offset parameter. A downlink control information is received. The downlink control information comprises: an uplink grant indicating second uplink resources of the uplink data channel; and an offset indicator value indicating one of the plurality of second offset parameters. A second UCI is transmitted via a number of the second uplink resources. The number of the second uplink resources is determined based on the offset indicator value.

FIG. 1 is a diagram depicting example sets of OFDM subcarriers as per anaspect of an embodiment of the present invention. As illustrated in thisexample, arrow(s) in the diagram may depict a subcarrier in amulticarrier OFDM system. The OFDM system may use technology such asOFDM technology, DFTS-OFDM, SC-OFDM technology, or the like. Forexample, arrow 101 shows a subcarrier transmitting information symbols.FIG. 1 is for illustration purposes, and a typical multicarrier OFDMsystem may include more subcarriers in a carrier. For example, thenumber of subcarriers in a carrier may be in the range of 10 to 10,000subcarriers. FIG. 1 shows two guard bands 106 and 107 in a transmissionband. As illustrated in FIG. 1, guard band 106 is between subcarriers103 and subcarriers 104. The example set of subcarriers A 102 includessubcarriers 103 and subcarriers 104. FIG. 1 also illustrates an exampleset of subcarriers B 105. As illustrated, there is no guard band betweenany two subcarriers in the example set of subcarriers B 105. Carriers ina multicarrier OFDM communication system may be contiguous carriers,non-contiguous carriers, or a combination of both contiguous andnon-contiguous carriers.

FIG. 2 is a diagram depicting an example transmission time and receptiontime for two carriers as per an aspect of an embodiment of the presentinvention. A multicarrier OFDM communication system may include one ormore carriers, for example, ranging from 1 to 10 carriers. Carrier A 204and carrier B 205 may have the same or different timing structures.Although FIG. 2 shows two synchronized carriers, carrier A 204 andcarrier B 205 may or may not be synchronized with each other. Differentradio frame structures may be supported for FDD and TDD duplexmechanisms. FIG. 2 shows an example FDD frame timing. Downlink anduplink transmissions may be organized into radio frames 201. In thisexample, radio frame duration is 10 msec. Other frame durations, forexample, in the range of 1 to 100 msec may also be supported. In thisexample, each 10 ms radio frame 201 may be divided into ten equallysized subframes 202. Other subframe durations such as including 0.5msec, 1 msec, 2 msec, and 5 msec may also be supported. Subframe(s) mayconsist of two or more slots (e.g. slots 206 and 207). For the exampleof FDD, 10 subframes may be available for downlink transmission and 10subframes may be available for uplink transmissions in each 10 msinterval. Uplink and downlink transmissions may be separated in thefrequency domain. A slot may be 7 or 14 OFDM symbols for the samesubcarrier spacing of up to 60 kHz with normal CP. A slot may be 14 OFDMsymbols for the same subcarrier spacing higher than 60 kHz with normalCP. A slot may contain all downlink, all uplink, or a downlink part andan uplink part and/or alike. Slot aggregation may be supported, e.g.,data transmission may be scheduled to span one or multiple slots. In anexample, a mini-slot may start at an OFDM symbol in a subframe. Amini-slot may have a duration of one or more OFDM symbols. Slot(s) mayinclude a plurality of OFDM symbols 203. The number of OFDM symbols 203in a slot 206 may depend on the cyclic prefix length and subcarrierspacing.

FIG. 3 is a diagram depicting OFDM radio resources as per an aspect ofan embodiment of the present invention. The resource grid structure intime 304 and frequency 305 is illustrated in FIG. 3. The quantity ofdownlink subcarriers or RBs may depend, at least in part, on thedownlink transmission bandwidth 306 configured in the cell. The smallestradio resource unit may be called a resource element (e.g. 301).Resource elements may be grouped into resource blocks (e.g. 302).Resource blocks may be grouped into larger radio resources calledResource Block Groups (RBG) (e.g. 303). The transmitted signal in slot206 may be described by one or several resource grids of a plurality ofsubcarriers and a plurality of OFDM symbols. Resource blocks may be usedto describe the mapping of certain physical channels to resourceelements. Other pre-defined groupings of physical resource elements maybe implemented in the system depending on the radio technology. Forexample, 24 subcarriers may be grouped as a radio block for a durationof 5 msec. In an illustrative example, a resource block may correspondto one slot in the time domain and 180 kHz in the frequency domain (for15 KHz subcarrier bandwidth and 12 subcarriers).

In an example embodiment, multiple numerologies may be supported. In anexample, a numerology may be derived by scaling a basic subcarrierspacing by an integer N. In an example, scalable numerology may allow atleast from 15 kHz to 480 kHz subcarrier spacing. The numerology with 15kHz and scaled numerology with different subcarrier spacing with thesame CP overhead may align at a symbol boundary every 1 ms in a NRcarrier.

FIG. 5A, FIG. 5B, FIG. 5C and FIG. 5D are example diagrams for uplinkand downlink signal transmission as per an aspect of an embodiment ofthe present invention. FIG. 5A shows an example uplink physical channel.The baseband signal representing the physical uplink shared channel mayperform the following processes. These functions are illustrated asexamples and it is anticipated that other mechanisms may be implementedin various embodiments. The functions may comprise scrambling,modulation of scrambled bits to generate complex-valued symbols, mappingof the complex-valued modulation symbols onto one or severaltransmission layers, transform precoding to generate complex-valuedsymbols, precoding of the complex-valued symbols, mapping of precodedcomplex-valued symbols to resource elements, generation ofcomplex-valued time-domain DFTS-OFDM/SC-FDMA signal for each antennaport, and/or the like.

An example structure for Downlink Transmissions is shown in FIG. 5C. Thebaseband signal representing a downlink physical channel may perform thefollowing processes. These functions are illustrated as examples and itis anticipated that other mechanisms may be implemented in variousembodiments. The functions include scrambling of coded bits in each ofthe codewords to be transmitted on a physical channel; modulation ofscrambled bits to generate complex-valued modulation symbols; mapping ofthe complex-valued modulation symbols onto one or several transmissionlayers; precoding of the complex-valued modulation symbols on each layerfor transmission on the antenna ports; mapping of complex-valuedmodulation symbols for each antenna port to resource elements;generation of complex-valued time-domain OFDM signal for each antennaport, and/or the like.

Example modulation and up-conversion to the carrier frequency of thecomplex-valued OFDM baseband signal for each antenna port is shown inFIG. 5D. Filtering may be employed prior to transmission.

The base station 401 may includeat least one communication interface 402, at least one processor 403,and at least one set of program code instructions 405 stored innon-transitory memory 404 and executable by the at least one processor403. The wireless device 406 may include at least one communicationinterface 407, at least one processor 408, and at least one set ofprogram code instructions 410 stored in non-transitory memory 409 andexecutable by the at least one processor 408. Communication interface402 in base station 401 may be configured to engage in communicationwith communication interface 407 in wireless device 406 via acommunication path that includes at least one wireless link 411.Wireless link 411 may be a bi-directional link. Communication interface407 in wireless device 406 may also be configured to engage in acommunication with communication interface 402 in base station 401. Basestation 401 and wireless device 406 may be configured to send andreceive data over wireless link 411 using multiple frequency carriers.According to some of the various aspects of embodiments, transceiver(s)may be employed. A transceiver is a device that includes both atransmitter and receiver. Transceivers may be employed in devices suchas wireless devices, base stations, relay nodes, and/or the like.Example embodiments for radio technology implemented in communicationinterface 402, 407 and wireless link 411 are illustrated are FIG. 1,FIG. 2, FIG. 3, FIG. 5, and associated text.

An interface may be a hardware interface, a firmware interface, asoftware interface, and/or a combination thereof. The hardware interfacemay include connectors, wires, electronic devices such as drivers,amplifiers, and/or the like. A software interface may include codestored in a memory device to implement protocol(s), protocol layers,communication drivers, device drivers, combinations thereof, and/or thelike. A firmware interface may include a combination of embeddedhardware and code stored in and/or in communication with a memory deviceto implement connections, electronic device operations, protocol(s),protocol layers, communication drivers, device drivers, hardwareoperations, combinations thereof, and/or the like.

The term configured may relate to the capacity of a device whether thedevice is in an operational or non-operational state. Configured mayalso refer to specific settings in a device that effect the operationalcharacteristics of the device whether the device is in an operational ornon-operational state. In other words, the hardware, software, firmware,registers, memory values, and/or the like may be “configured” within adevice, whether the device is in an operational or nonoperational state,to provide the device with specific characteristics. Terms such as “acontrol message to cause in a device” may mean that a control messagehas parameters that may be used to configure specific characteristics inthe device, whether the device is in an operational or non-operationalstate.

According to some of the various aspects of embodiments, a 5G networkmay include a multitude of base stations, providing a user plane NRPDCP/NR RLC/NR MAC/NR PHY and control plane (NR RRC) protocolterminations towards the wireless device. The base station(s) may beinterconnected with other base station(s) (e.g. employing an Xninterface). The base stations may also be connected employing, forexample, an NG interface to an NGC. FIG. 10A and FIG. 10B are examplediagrams for interfaces between a 5G core network (e.g. NGC) and basestations (e.g. gNB and eLTE eNB) as per an aspect of an embodiment ofthe present invention. For example, the base stations may beinterconnected to the NGC control plane (e.g. NG CP) employing the NG-Cinterface and to the NGC user plane (e.g. UPGW) employing the NG-Uinterface. The NG interface may support a many-to-many relation between5G core networks and base stations.

A base station may include many sectors for example: 1, 2, 3, 4, or 6sectors. A base station may include many cells, for example, rangingfrom 1 to 50 cells or more. A cell may be categorized, for example, as aprimary cell or secondary cell. At RRC connectionestablishment/re-establishment/handover, one serving cell may providethe NAS (non-access stratum) mobility information (e.g. TAI), and at RRCconnection re-establishment/handover, one serving cell may provide thesecurity input. This cell may be referred to as the Primary Cell(PCell). In the downlink, the carrier corresponding to the PCell may bethe Downlink Primary Component Carrier (DL PCC), while in the uplink, itmay be the Uplink Primary Component Carrier (UL PCC). Depending onwireless device capabilities, Secondary Cells (SCells) may be configuredto form together with the PCell a set of serving cells. In the downlink,the carrier corresponding to an SCell may be a Downlink SecondaryComponent Carrier (DL SCC), while in the uplink, it may be an UplinkSecondary Component Carrier (UL SCC). An SCell may or may not have anuplink carrier.

A cell, comprising a downlink carrier and optionally an uplink carrier,may be assigned a physical cell ID and a cell index. A carrier (downlinkor uplink) may belong to only one cell. The cell ID or Cell index mayalso identify the downlink carrier or uplink carrier of the cell(depending on the context it is used). In the specification, cell ID maybe equally referred to a carrier ID, and cell index may be referred tocarrier index. In implementation, the physical cell ID or cell index maybe assigned to a cell. A cell ID may be determined using asynchronization signal transmitted on a downlink carrier. A cell indexmay be determined using RRC messages. For example, when thespecification refers to a first physical cell ID for a first downlinkcarrier, the specification may mean the first physical cell ID is for acell comprising the first downlink carrier. The same concept may applyto, for example, carrier activation. When the specification indicatesthat a first carrier is activated, the specification may equally meanthat the cell comprising the first carrier is activated.

Embodiments may be configured to operate as needed. The disclosedmechanism may be performed when certain criteria are met, for example,in a wireless device, a base station, a radio environment, a network, acombination of the above, and/or the like. Example criteria may bebased, at least in part, on for example, traffic load, initial systemset up, packet sizes, traffic characteristics, a combination of theabove, and/or the like. When the one or more criteria are met, variousexample embodiments may be applied. Therefore, it may be possible toimplement example embodiments that selectively implement disclosedprotocols.

A base station may communicate with a mix of wireless devices. Wirelessdevices may support multiple technologies, and/or multiple releases ofthe same technology. Wireless devices may have some specificcapability(ies) depending on its wireless device category and/orcapability(ies). A base station may comprise multiple sectors. When thisdisclosure refers to a base station communicating with a plurality ofwireless devices, this disclosure may refer to a subset of the totalwireless devices in a coverage area. This disclosure may refer to, forexample, a plurality of wireless devices of a given LTE or 5G releasewith a given capability and in a given sector of the base station. Theplurality of wireless devices in this disclosure may refer to a selectedplurality of wireless devices, and/or a subset of total wireless devicesin a coverage area which perform according to disclosed methods, and/orthe like. There may be a plurality of wireless devices in a coveragearea that may not comply with the disclosed methods, for example,because those wireless devices perform based on older releases of LTE or5G technology.

FIG. 6 and FIG. 7 are example diagrams for protocol structure with CAand multi-connectivity as per an aspect of an embodiment of the presentinvention. NR may support multi-connectivity operation whereby amultiple RX/TX UE in RRC_CONNECTED may be configured to utilize radioresources provided by multiple schedulers located in multiple gNBsconnected via a non-ideal or ideal backhaul over the Xn interface. gNBsinvolved in multi-connectivity for a certain UE may assume two differentroles: a gNB may either act as a master gNB or as a secondary gNB. Inmulti-connectivity, a UE may be connected to one master gNB and one ormore secondary gNBs. FIG. 7 illustrates one example structure for the UEside MAC entities when a Master Cell Group (MCG) and a Secondary CellGroup (SCG) are configured, and it may not restrict implementation.Media Broadcast Multicast Service (MBMS) reception is not shown in thisfigure for simplicity.

In multi-connectivity, the radio protocol architecture that a particularbearer uses may depend on how the bearer is setup. Three alternativesmay exist, an MCG bearer, an SCG bearer and a split bearer as shown inFIG. 6. NR RRC may be located in master gNB and SRBs may be configuredas a MCG bearer type and may use the radio resources of the master gNB.Multi-connectivity may also be described as having at least one bearerconfigured to use radio resources provided by the secondary gNB.Multi-connectivity may or may not be configured/implemented in exampleembodiments of the invention.

In the case of multi-connectivity, the UE may be configured withmultiple NR MAC entities: one NR MAC entity for master gNB, and other NRMAC entities for secondary gNBs. In multi-connectivity, the configuredset of serving cells for a UE may comprise of two subsets: the MasterCell Group (MCG) containing the serving cells of the master gNB, and theSecondary Cell Groups (SCGs) containing the serving cells of thesecondary gNBs. For a SCG, one or more of the following may be applied:at least one cell in the SCG has a configured UL CC and one of them,named PSCell (or PCell of SCG, or sometimes called PCell), is configuredwith PUCCH resources; when the SCG is configured, there may be at leastone SCG bearer or one Split bearer; upon detection of a physical layerproblem or a random access problem on a PSCell, or the maximum number ofNR RLC retransmissions has been reached associated with the SCG, or upondetection of an access problem on a PSCell during a SCG addition or aSCG change: a RRC connection re-establishment procedure may not betriggered, UL transmissions towards cells of the SCG are stopped, amaster gNB may be informed by the UE of a SCG failure type, for splitbearer, the DL data transfer over the master gNB is maintained; the NRRLC AM bearer may be configured for the split bearer; like PCell, PSCellmay not be de-activated; PSCell may be changed with a SCG change (e.g.with security key change and a RACH procedure); and/or a direct bearertype change between a Split bearer and a SCG bearer or simultaneousconfiguration of a SCG and a Split bearer may or may not supported.

With respect to the interaction between a master gNB and secondary gNB sfor multi-connectivity, one or more of the following principles may beapplied: the master gNB may maintain the RRM measurement configurationof the UE and may, (e.g, based on received measurement reports ortraffic conditions or bearer types), decide to ask a secondary gNB toprovide additional resources (serving cells) for a UE; upon receiving arequest from the master gNB, a secondary gNB may create a container thatmay result in the configuration of additional serving cells for the UE(or decide that it has no resource available to do so); for UEcapability coordination, the master gNB may provide (part of) the ASconfiguration and the UE capabilities to the secondary gNB; the mastergNB and the secondary gNB may exchange information about a UEconfiguration by employing of NR RRC containers (inter-node messages)carried in Xn messages; the secondary gNB may initiate a reconfigurationof its existing serving cells (e.g., PUCCH towards the secondary gNB);the secondary gNB may decide which cell is the PSCell within the SCG;the master gNB may or may not change the content of the NR RRCconfiguration provided by the secondary gNB; in the case of a SCGaddition and a SCG SCell addition, the master gNB may provide the latestmeasurement results for the SCG cell(s); both a master gNB and secondarygNBs may know the SFN and subframe offset of each other by OAM, (e.g.,for the purpose of DRX alignment and identification of a measurementgap). In an example, when adding a new SCG SCell, dedicated NR RRCsignaling may be used for sending required system information of thecell as for CA, except for the SFN acquired from a MIB of the PSCell ofa SCG.

In an example, serving cells may be grouped in a TA group (TAG). Servingcells in one TAG may use the same timing reference. For a given TAG,user equipment (UE) may use at least one downlink carrier as a timingreference. For a given TAG, a UE may synchronize uplink subframe andframe transmission timing of uplink carriers belonging to the same TAG.In an example, serving cells having an uplink to which the same TAapplies may correspond to serving cells hosted by the same receiver. AUE supporting multiple TAs may support two or more TA groups. One TAgroup may contain the PCell and may be called a primary TAG (pTAG). In amultiple TAG configuration, at least one TA group may not contain thePCell and may be called a secondary TAG (sTAG). In an example, carrierswithin the same TA group may use the same TA value and/or the sametiming reference. When DC is configured, cells belonging to a cell group(MCG or SCG) may be grouped into multiple TAGs including a pTAG and oneor more sTAGs.

FIG. 8 shows example TAG configurations as per an aspect of anembodiment of the present invention. In Example 1, pTAG comprises PCell,and an sTAG comprises SCell1. In Example 2, a pTAG comprises a PCell andSCell1, and an sTAG comprises SCell2 and SCell3. In Example 3, pTAGcomprises PCell and SCell1, and an sTAG1 includes SCell2 and SCell3, andsTAG2 comprises SCell4. Up to four TAGs may be supported in a cell group(MCG or SCG) and other example TAG configurations may also be provided.In various examples in this disclosure, example mechanisms are describedfor a pTAG and an sTAG. Some of the example mechanisms may be applied toconfigurations with multiple sTAGs.

In an example, an eNB may initiate an RA procedure via a PDCCH order foran activated SCell. This PDCCH order may be sent on a scheduling cell ofthis SCell. When cross carrier scheduling is configured for a cell, thescheduling cell may be different than the cell that is employed forpreamble transmission, and the PDCCH order may include an SCell index.At least a non-contention based RA procedure may be supported forSCell(s) assigned to sTAG(s).

FIG. 9 is an example message flow in a random access process in asecondary TAG as per an aspect of an embodiment of the presentinvention. An eNB transmits an activation command 600 to activate anSCell. A preamble 602 (Msg1) may be sent by a UE in response to a PDCCHorder 601 on an SCell belonging to an sTAG. In an example embodiment,preamble transmission for SCells may be controlled by the network usingPDCCH format 1A. Msg2 message 603 (RAR: random access response) inresponse to the preamble transmission on the SCell may be addressed toRA-RNTI in a PCell common search space (CSS). Uplink packets 604 may betransmitted on the SCell in which the preamble was transmitted.

According to some of the various aspects of embodiments, initial timingalignment may be achieved through a random access procedure. This mayinvolve a UE transmitting a random access preamble and an eNB respondingwith an initial TA command NTA (amount of timing advance) within arandom access response window. The start of the random access preamblemay be aligned with the start of a corresponding uplink subframe at theUE assuming NTA=0. The eNB may estimate the uplink timing from therandom access preamble transmitted by the UE. The TA command may bederived by the eNB based on the estimation of the difference between thedesired UL timing and the actual UL timing. The UE may determine theinitial uplink transmission timing relative to the correspondingdownlink of the sTAG on which the preamble is transmitted.

The mapping of a serving cell to a TAG may be configured by a servingeNB with RRC signaling. The mechanism for TAG configuration andreconfiguration may be based on RRC signaling. According to some of thevarious aspects of embodiments, when an eNB performs an SCell additionconfiguration, the related TAG configuration may be configured for theSCell. In an example embodiment, an eNB may modify the TAG configurationof an SCell by removing (releasing) the SCell and adding(configuring) anew SCell (with the same physical cell ID and frequency) with an updatedTAG ID. The new SCell with the updated TAG ID may initially be inactivesubsequent to being assigned the updated TAG ID. The eNB may activatethe updated new SCell and start scheduling packets on the activatedSCell. In an example implementation, it may not be possible to changethe TAG associated with an SCell, but rather, the SCell may need to beremoved and a new SCell may need to be added with another TAG. Forexample, if there is a need to move an SCell from an sTAG to a pTAG, atleast one RRC message, for example, at least one RRC reconfigurationmessage, may be send to the UE to reconfigure TAG configurations byreleasing the SCell and then configuring the SCell as a part of the pTAG(when an SCell is added/configured without a TAG index, the SCell may beexplicitly assigned to the pTAG). The PCell may not change its TA groupand may be a member of the pTAG.

The purpose of an RRC connection reconfiguration procedure may be tomodify an RRC connection, (e.g. to establish, modify and/or release RBs, to perform handover, to setup, modify, and/or release measurements,to add, modify, and/or release SCells). If the received RRC ConnectionReconfiguration message includes the sCellToReleaseList, the UE mayperform an SCell release. If the received RRC Connection Reconfigurationmessage includes the sCellToAddModList, the UE may perform SCelladditions or modification.

In LTE Release-10 and Release-11 CA, a PUCCH is only transmitted on thePCell (PSCell) to an eNB. In LTE-Release 12 and earlier, a UE maytransmit PUCCH information on one cell (PCell or PSCell) to a given eNB.

As the number of CA capable UEs and also the number of aggregatedcarriers increase, the number of PUCCHs and also the PUCCH payload sizemay increase. Accommodating the PUCCH transmissions on the PCell maylead to a high PUCCH load on the PCell. A PUCCH on an SCell may beintroduced to offload the PUCCH resource from the PCell. More than onePUCCH may be configured for example, a PUCCH on a PCell and anotherPUCCH on an SCell. In the example embodiments, one, two or more cellsmay be configured with PUCCH resources for transmitting CSI/ACK/NACK toa base station. Cells may be grouped into multiple PUCCH groups, and oneor more cell within a group may be configured with a PUCCH. In anexample configuration, one SCell may belong to one PUCCH group. SCellswith a configured PUCCH transmitted to a base station may be called aPUCCH SCell, and a cell group with a common PUCCH resource transmittedto the same base station may be called a PUCCH group.

In an example embodiment, a MAC entity may have a configurable timertimeAlignmentTimer per TAG. The timeAlignmentTimer may be used tocontrol how long the MAC entity considers the Serving Cells belonging tothe associated TAG to be uplink time aligned. The MAC entity may, when aTiming Advance Command MAC control element is received, apply the TimingAdvance Command for the indicated TAG; start or restart thetimeAlignmentTimer associated with the indicated TAG. The MAC entitymay, when a Timing Advance Command is received in a Random AccessResponse message for a serving cell belonging to a TAG and/or if theRandom Access Preamble was not selected by the MAC entity, apply theTiming Advance Command for this TAG and start or restart thetimeAlignmentTimer associated with this TAG. Otherwise, if thetimeAlignmentTimer associated with this TAG is not running, the TimingAdvance Command for this TAG may be applied and the timeAlignmentTimerassociated with this TAG started. When the contention resolution isconsidered not successful, a timeAlignmentTimer associated with this TAGmay be stopped. Otherwise, the MAC entity may ignore the received TimingAdvance Command.

In example embodiments, a timer is running once it is started, until itis stopped or until it expires; otherwise it may not be running. A timercan be started if it is not running or restarted if it is running. Forexample, a timer may be started or restarted from its initial value.

FIG. 11A, FIG. 11B, FIG. 11C, FIG. 11D, FIG. 11E, and FIG. 11F areexample diagrams for architectures of tight interworking between 5G RANand LTE RAN as per an aspect of an embodiment of the present invention.The tight interworking may enable a multiple RX/TX UE in RRC_CONNECTEDto be configured to utilize radio resources provided by two schedulerslocated in two base stations (e.g. (e)LTE eNB and gNB) connected via anon-ideal or ideal backhaul over the Xx interface between LTE eNB andgNB or the Xn interface between eLTE eNB and gNB. Base stations involvedin tight interworking for a certain UE may assume two different roles: abase station may either act as a master base station or as a secondarybase station. In tight interworking, a UE may be connected to one masterbase station and one secondary base station. Mechanisms implemented intight interworking may be extended to cover more than two base stations.

In FIG. 11A and FIG. 11B, a master base station may be an LTE eNB, whichmay be connected to EPC nodes (e.g. to an MME via the S1-C interface andto an S-GW via the S1-U interface), and a secondary base station may bea gNB, which may be a non-standalone node having a control planeconnection via an Xx-C interface to an LTE eNB. In the tightinterworking architecture of FIG. 11A, a user plane for a gNB may beconnected to an S-GW through an LTE eNB via an Xx-U interface betweenLTE eNB and gNB and an S1-U interface between LTE eNB and S-GW. In thearchitecture of FIG. 11B, a user plane for a gNB may be connecteddirectly to an S-GW via an S1-U interface between gNB and S-GW.

In FIG. 11C and FIG. 11D, a master base station may be a gNB, which maybe connected to NGC nodes (e.g. to a control plane core node via theNG-C interface and to a user plane core node via the NG-U interface),and a secondary base station may be an eLTE eNB, which may be anon-standalone node having a control plane connection via an Xn-Cinterface to a gNB. In the tight interworking architecture of FIG. 11C,a user plane for an eLTE eNB may be connected to a user plane core nodethrough a gNB via an Xn-U interface between eLTE eNB and gNB and an NG-Uinterface between gNB and user plane core node. In the architecture ofFIG. 11D, a user plane for an eLTE eNB may be connected directly to auser plane core node via an NG-U interface between eLTE eNB and userplane core node.

In FIG. 11E and FIG. 11F, a master base station may be an eLTE eNB,which may be connected to NGC nodes (e.g. to a control plane core nodevia the NG-C interface and to a user plane core node via the NG-Uinterface), and a secondary base station may be a gNB, which may be anon-standalone node having a control plane connection via an Xn-Cinterface to an eLTE eNB. In the tight interworking architecture of FIG.11E, a user plane for a gNB may be connected to a user plane core nodethrough an eLTE eNB via an Xn-U interface between eLTE eNB and gNB andan NG-U interface between eLTE eNB and user plane core node. In thearchitecture of FIG. 11F, a user plane for a gNB may be connecteddirectly to a user plane core node via an NG-U interface between gNB anduser plane core node.

FIG. 12A, FIG. 12B, and FIG. 12C are example diagrams for radio protocolstructures of tight interworking bearers as per an aspect of anembodiment of the present invention. In FIG. 12A, an LTE eNB may be amaster base station, and a gNB may be a secondary base station. In FIG.12B, a gNB may be a master base station, and an eLTE eNB may be asecondary base station. In FIG. 12C, an eLTE eNB may be a master basestation, and a gNB may be a secondary base station. In 5G network, theradio protocol architecture that a particular bearer uses may depend onhow the bearer is setup. Three alternatives may exist, an MCG bearer, anSCG bearer, and a split bearer as shown in FIG. 12A, FIG. 12B, and FIG.12C. NR RRC may be located in master base station, and SRBs may beconfigured as an MCG bearer type and may use the radio resources of themaster base station. Tight interworking may also be described as havingat least one bearer configured to use radio resources provided by thesecondary base station. Tight interworking may or may not beconfigured/implemented in example embodiments of the invention.

In the case of tight interworking, the UE may be configured with two MACentities: one MAC entity for master base station, and one MAC entity forsecondary base station. In tight interworking, the configured set ofserving cells for a UE may comprise of two subsets: the Master CellGroup (MCG) containing the serving cells of the master base station, andthe Secondary Cell Group (SCG) containing the serving cells of thesecondary base station. For a SCG, one or more of the following may beapplied: at least one cell in the SCG has a configured UL CC and one ofthem, named PSCell (or PCell of SCG, or sometimes called PCell), isconfigured with PUCCH resources; when the SCG is configured, there maybe at least one SCG bearer or one split bearer; upon detection of aphysical layer problem or a random access problem on a PSCell, or themaximum number of (NR) RLC retransmissions has been reached associatedwith the SCG, or upon detection of an access problem on a PSCell duringa SCG addition or a SCG change: a RRC connection re-establishmentprocedure may not be triggered, UL transmissions towards cells of theSCG are stopped, a master base station may be informed by the UE of aSCG failure type, for split bearer, the DL data transfer over the masterbase station is maintained; the RLC AM bearer may be configured for thesplit bearer; like PCell, PSCell may not be de-activated; PSCell may bechanged with a SCG change (e.g. with security key change and a RACHprocedure); and/or neither a direct bearer type change between a Splitbearer and a SCG bearer nor simultaneous configuration of a SCG and aSplit bearer are supported.

With respect to the interaction between a master base station and asecondary base station, one or more of the following principles may beapplied: the master base station may maintain the RRM measurementconfiguration of the UE and may, (e.g, based on received measurementreports, traffic conditions, or bearer types), decide to ask a secondarybase station to provide additional resources (serving cells) for a UE;upon receiving a request from the master base station, a secondary basestation may create a container that may result in the configuration ofadditional serving cells for the UE (or decide that it has no resourceavailable to do so); for UE capability coordination, the master basestation may provide (part of) the AS configuration and the UEcapabilities to the secondary base station; the master base station andthe secondary base station may exchange information about a UEconfiguration by employing of RRC containers (inter-node messages)carried in Xn or Xx messages; the secondary base station may initiate areconfiguration of its existing serving cells (e.g., PUCCH towards thesecondary base station); the secondary base station may decide whichcell is the PSCell within the SCG; the master base station may notchange the content of the RRC configuration provided by the secondarybase station; in the case of a SCG addition and a SCG SCell addition,the master base station may provide the latest measurement results forthe SCG cell(s); both a master base station and a secondary base stationmay know the SFN and subframe offset of each other by OAM, (e.g., forthe purpose of DRX alignment and identification of a measurement gap).In an example, when adding a new SCG SCell, dedicated RRC signaling maybe used for sending required system information of the cell as for CA,except for the SFN acquired from a MIB of the PSCell of a SCG.

FIG. 13A and FIG. 13B are example diagrams for gNB deployment scenariosas per an aspect of an embodiment of the present invention. In thenon-centralized deployment scenario in FIG. 13A, the full protocol stack(e.g. NR RRC, NR PDCP, NR RLC, NR MAC, and NR PHY) may be supported atone node. In the centralized deployment scenario in FIG. 13B, upperlayers of gNB may be located in a Central Unit (CU), and lower layers ofgNB may be located in Distributed Units (DU). The CU-DU interface (e.g.Fs interface) connecting CU and DU may be ideal or non-ideal. Fs-C mayprovide a control plane connection over Fs interface, and Fs-U mayprovide a user plane connection over Fs interface. In the centralizeddeployment, different functional split options between CU and DUs may bepossible by locating different protocol layers (RAN functions) in CU andDU. The functional split may support flexibility to move RAN functionsbetween CU and DU depending on service requirements and/or networkenvironments. The functional split option may change during operationafter Fs interface setup procedure, or may change only in Fs setupprocedure (i.e. static during operation after Fs setup procedure).

FIG. 14 is an example diagram for different functional split optionexamples of the centralized gNB deployment scenario as per an aspect ofan embodiment of the present invention. In the split option example 1,an NR RRC may be in CU, and NR PDCP, NR RLC, NR MAC, NR PHY, and RF maybe in DU. In the split option example 2, an NR RRC and NR PDCP may be inCU, and NR RLC, NR MAC, NR PHY, and RF may be in DU. In the split optionexample 3, an NR RRC, NR PDCP, and partial function of NR RLC may be inCU, and the other partial function of NR RLC, NR MAC, NR PHY, and RF maybe in DU. In the split option example 4, an NR RRC, NR PDCP, and NR RLCmay be in CU, and NR MAC, NR PHY, and RF may be in DU. In the splitoption example 5, an NR RRC, NR PDCP, NR RLC, and partial function of NRMAC may be in CU, and the other partial function of NR MAC, NR PHY, andRF may be in DU. In the split option example 6, an NR RRC, NR PDCP, NRRLC, and NR MAC may be in CU, and NR PHY and RF may be in DU. In thesplit option example 7, an NR RRC, NR PDCP, NR RLC, NR MAC, and partialfunction of NR PHY may be in CU, and the other partial function of NRPHY and RF may be in DU. In the split option example 8, an NR RRC, NRPDCP, NR RLC, NR MAC, and NR PHY may be in CU, and RF may be in DU.

The functional split may be configured per CU, per DU, per UE, perbearer, per slice, or with other granularities. In per CU split, a CUmay have a fixed split, and DUs may be configured to match the splitoption of CU. In per DU split, each DU may be configured with adifferent split, and a CU may provide different split options fordifferent DUs. In per UE split, a gNB (CU and DU) may provide differentsplit options for different UEs. In per bearer split, different splitoptions may be utilized for different bearer types. In per slice splice,different split options may be applied for different slices.

In an example embodiment, the new radio access network (new RAN) maysupport different network slices, which may allow differentiatedtreatment customized to support different service requirements with endto end scope. The new RAN may provide a differentiated handling oftraffic for different network slices that may be pre-configured, and mayallow a single RAN node to support multiple slices. The new RAN maysupport selection of a RAN part for a given network slice, by one ormore slice ID(s) or NSSAI(s) provided by a UE or a NGC (e.g. NG CP). Theslice ID(s) or NSSAI(s) may identify one or more of pre-configurednetwork slices in a PLMN. For initial attach, a UE may provide a sliceID and/or an NSSAI, and a RAN node (e.g. gNB) may use the slice ID orthe NSSAI for routing an initial NAS signaling to an NGC control planefunction (e.g. NG CP). If a UE does not provide any slice ID or NSSAI, aRAN node may send a NAS signaling to a default NGC control planefunction. For subsequent accesses, the UE may provide a temporary ID fora slice identification, which may be assigned by the NGC control planefunction, to enable a RAN node to route the NAS message to a relevantNGC control plane function. The new RAN may support resource isolationbetween slices. The RAN resource isolation may be achieved by avoidingthat shortage of shared resources in one slice breaks a service levelagreement for another slice.

The amount of data traffic carried over cellular networks is expected toincrease for many years to come. The number of users/devices isincreasing and each user/device accesses an increasing number andvariety of services, e.g. video delivery, large files, images. Thisrequires not only high capacity in the network, but also provisioningvery high data rates to meet customers' expectations on interactivityand responsiveness. More spectrum is therefore needed for cellularoperators to meet the increasing demand. Considering user expectationsof high data rates along with seamless mobility, it is beneficial thatmore spectrum be made available for deploying macro cells as well assmall cells for cellular systems.

Striving to meet the market demands, there has been increasing interestfrom operators in deploying some complementary access utilizingunlicensed spectrum to meet the traffic growth. This is exemplified bythe large number of operator-deployed Wi-Fi networks and the 3GPPstandardization of LTE/WLAN interworking solutions. This interestindicates that unlicensed spectrum, when present, can be an effectivecomplement to licensed spectrum for cellular operators to helpaddressing the traffic explosion in some scenarios, such as hotspotareas. LAA offers an alternative for operators to make use of unlicensedspectrum while managing one radio network, thus offering newpossibilities for optimizing the network's efficiency.

In an example embodiment, Listen-before-talk (clear channel assessment)may be implemented for transmission in an LAA cell. In alisten-before-talk (LBT) procedure, equipment may apply a clear channelassessment (CCA) check before using the channel. For example, the CCAutilizes at least energy detection to determine the presence or absenceof other signals on a channel in order to determine if a channel isoccupied or clear, respectively. For example, European and Japaneseregulations mandate the usage of LBT in the unlicensed bands. Apart fromregulatory requirements, carrier sensing via LBT may be one way for fairsharing of the unlicensed spectrum.

In an example embodiment, discontinuous transmission on an unlicensedcarrier with limited maximum transmission duration may be enabled. Someof these functions may be supported by one or more signals to betransmitted from the beginning of a discontinuous LAA downlinktransmission. Channel reservation may be enabled by the transmission ofsignals, by an LAA node, after gaining channel access via a successfulLBT operation, so that other nodes that receive the transmitted signalwith energy above a certain threshold sense the channel to be occupied.Functions that may need to be supported by one or more signals for LAAoperation with discontinuous downlink transmission may include one ormore of the following: detection of the LAA downlink transmission(including cell identification) by UEs; time & frequency synchronizationof UEs.

In an example embodiment, DL LAA design may employ subframe boundaryalignment according to LTE-A carrier aggregation timing relationshipsacross serving cells aggregated by CA. This may not imply that the eNBtransmissions can start only at the subframe boundary. LAA may supporttransmitting PDSCH when not all OFDM symbols are available fortransmission in a subframe according to LBT. Delivery of necessarycontrol information for the PDSCH may also be supported.

LBT procedure may be employed for fair and friendly coexistence of LAAwith other operators and technologies operating in unlicensed spectrum.LBT procedures on a node attempting to transmit on a carrier inunlicensed spectrum require the node to perform a clear channelassessment to determine if the channel is free for use. An LBT proceduremay involve at least energy detection to determine if the channel isbeing used. For example, regulatory requirements in some regions, e.g.,in Europe, specify an energy detection threshold such that if a nodereceives energy greater than this threshold, the node assumes that thechannel is not free. While nodes may follow such regulatoryrequirements, a node may optionally use a lower threshold for energydetection than that specified by regulatory requirements. In an example,LAA may employ a mechanism to adaptively change the energy detectionthreshold, e.g., LAA may employ a mechanism to adaptively lower theenergy detection threshold from an upper bound. Adaptation mechanism maynot preclude static or semi-static setting of the threshold. In anexample Category 4 LBT mechanism or other type of LBT mechanisms may beimplemented.

Various example LBT mechanisms may be implemented. In an example, forsome signals, in some implementation scenarios, in some situations,and/or in some frequencies no LBT procedure may performed by thetransmitting entity. In an example, Category 2 (e.g. LBT without randomback-off) may be implemented. The duration of time that the channel issensed to be idle before the transmitting entity transmits may bedeterministic. In an example, Category 3 (e.g. LBT with random back-offwith a contention window of fixed size) may be implemented. The LBTprocedure may have the following procedure as one of its components. Thetransmitting entity may draw a random number N within a contentionwindow. The size of the contention window may be specified by theminimum and maximum value of N. The size of the contention window may befixed. The random number N may be employed in the LBT procedure todetermine the duration of time that the channel is sensed to be idlebefore the transmitting entity transmits on the channel. In an example,Category 4 (e.g. LBT with random back-off with a contention window ofvariable size) may be implemented. The transmitting entity may draw arandom number N within a contention window. The size of contentionwindow may be specified by the minimum and maximum value of N. Thetransmitting entity may vary the size of the contention window whendrawing the random number N. The random number N is used in the LBTprocedure to determine the duration of time that the channel is sensedto be idle before the transmitting entity transmits on the channel.

LAA may employ uplink LBT at the UE. The UL LBT scheme may be differentfrom the DL LBT scheme (e.g. by using different LBT mechanisms orparameters) for example, since the LAA UL is based on scheduled accesswhich affects a UE's channel contention opportunities. Otherconsiderations motivating a different UL LBT scheme include, but are notlimited to, multiplexing of multiple UEs in a single subframe.

In an example, a DL transmission burst may be a continuous transmissionfrom a DL transmitting node with no transmission immediately before orafter from the same node on the same CC. An UL transmission burst from aUE perspective may be a continuous transmission from a UE with notransmission immediately before or after from the same UE on the sameCC. In an example, UL transmission burst is defined from a UEperspective. In an example, an UL transmission burst may be defined froman eNB perspective. In an example, in case of an eNB operating DL+UL LAAover the same unlicensed carrier, DL transmission burst(s) and ULtransmission burst(s) on LAA may be scheduled in a TDM manner over thesame unlicensed carrier. For example, an instant in time may be part ofa DL transmission burst or an UL transmission burst.

In an example, a wireless device may receive one or more messagescomprising one or more radio resource configuration (RRC) messages fromone or more base stations (e.g., one or more NR gNBs and/or one or moreLTE eNBs and/or one or more eLTE eNBs, etc.). In an example, the one ormore messages may comprise configuration parameters for a plurality oflogical channels. In an example, the one or more messages may comprise alogical channel identifier for each of the plurality of logicalchannels. In an example, the logical channel identifier may be one of aplurality of logical channel identifiers. In an example, the pluralityof logical channel identifiers may be pre-configured. In an example, thelogical channel identifier may be one of a plurality of consecutiveintegers.

In an example, the plurality of logical channels configured for awireless device may correspond to one or more bearers. In an example,there may be one-to-one mapping/correspondence between a bearer and alogical channel. In an example, there may be one-to-manymapping/correspondence between one or more bearers and one or morelogical channels. In an example, a bearer may be mapped to a pluralityof logical channels. In an example, data from a packet data convergenceprotocol (PDCP) entity corresponding to a bearer may be duplicated andmapped to a plurality of radio link control (RLC) entities and/orlogical channels. In an example, scheduling of the plurality of logicalchannels may be performed by a single medium access control (MAC)entity. In an example, scheduling of the plurality of logical channelsmay be performed by a two or more MAC entities. In an example, a logicalchannel may be scheduled by one of a plurality of MAC entities. In anexample, the one or more bearers may comprise one or more data radiobearers. In an example, the one or more bearers may comprise one or moresignaling radio bearers. In an example, the one or more bearers maycorrespond to one or more application and/or quality of service (QoS)requirements. In an example, one or more bearers may correspond toultra-reliable low latency communications (URLLC) applications and/orenhanced mobile broadband (eMBB) applications and/or massive machine tomachine communications (mMTC) applications.

In an example, a first logical channel of the plurality of logicalchannels may be mapped to one or more of a plurality of transmissiontime intervals (TTIs)/numerologies. In an example, a logical channel maynot be mapped to one or more of the plurality of TTIs/numerologies. Inan example, a logical channel corresponding to a URLLC bearer may bemapped to one or more first TTIs and a logical corresponding to an eMBBapplication may be mapped to one or more second TTIs, wherein the one ormore first TTIs may have shorter duration than the one or more secondTTIs. In an example, the plurality of TTIs/numerologies may bepre-configured at the wireless device. In an example, the one or moremessages may comprise the configuration parameters of the plurality ofTTIs/numerologies. In an example, a base station may transmit agrant/DCI to a wireless device, wherein the grant/DCI may compriseindication of a cell and/or a TTI/numerology that the wireless devicemay transmit data. In an example, a first field in the grant/DCI mayindicate the cell and a second field in the grant/DCI may indicate theTTI/numerology. In an example, a field in the grant/DCI may indicateboth the cell and the TTI/numerology.

In an example, the one or more messages may comprise a logical channelgroup identifier for one or more of the plurality of the logicalchannels. In an example, one or more of the plurality of logicalchannels may be assigned a logical channel group identifier n, 0≤n≤N(e.g., N=3, or 5, or 7, or 11 or 15, etc.). In an example, the one ormore of the plurality of logical channels with the logical channel groupidentifier may be mapped to a same one or more TTIs/numerologies. In anexample, the one or more of the plurality of logical channels with thelogical channel group identifier may only be mapped to a same one ormore TTIs/numerologies. In an example, the one more of the plurality oflogical channels may correspond to a same application and/or QoSrequirements. In an example, a first one or more logical channels may beassigned logical channel identifier(s) and logical channel groupidentifier(s) and a second one or more logical channels may be assignedlogical channel identifier(s). In an example, a logical channel groupmay comprise of one logical channel.

In an example, the one or more messages may comprise one or more firstfields indicating mapping between the plurality of logical channels andthe plurality of TTIs/numerologies and/or cells. In an example, the oneor more first fields may comprise a first value indicating a logicalchannel is mapped to one or more first TTI duration shorter than orequal to the first value. In an example, the one or more first fieldsmay comprise a second value indicating a logical channel is mapped toone or more second TTI durations longer than or equal to the secondvalue. In an example, the one or more first fields may comprise and/orindicate one or more TTIs/numerologies and/or cells that a logicalchannel is mapped to. In an example, the mapping may be indicated usingone or more bitmaps. In an example, if a value of 1 in a bitmapassociated with a logical channel may indicate that the logical channelis mapped to a corresponding TTI/numerology and/or cell. In an example,if a value of 0 in the bitmap associated with a logical channel mayindicate that the logical channel is not mapped to a correspondingTTI/numerology and/or cell. In an example, the one or more messages maycomprise configuration parameters for the plurality of the logicalchannels. In an example, the configuration parameters for a logicalchannel may comprise an associated bitmap for the logical channelwherein the bitmap may indicate the mapping between the logical channeland the plurality of TTIs/numerologies and/or cells.

In an example, a first logical channel may be assigned at least a firstlogical channel priority. In an example, the first logical channel maybe assigned one or more logical channel priorities for one or moreTTIs/numerologies. In an example, the first logical channel may beassigned a logical channel priority for each of the plurality ofTTIs/numerologies. In an example, a logical channel may be assigned alogical channel priority for each of one or more of the plurality ofTTIs/numerologies. In an example, a logical channel may be assigned alogical channel priority for each of one or more TTIs/numerologieswherein the logical channel is mapped to the each of the one or moreTTIs/numerologies. In an example, the one or more messages may compriseone or more second fields indicating priorities of a logical channel onone or more TTIs/numerologies. In an example, the one or more secondfields may comprise one or more sequences indicating priorities of alogical channel on one or more TTIs/numerologies. In an example, the oneor more second fields may comprise a plurality of sequences for theplurality of logical channels. A sequence corresponding to a logicalchannel may indicate the priorities of the logical channel on theplurality of TTIs/numerologies/cells or one or more of the plurality ofTTIs/numerologies/cells. In an example, the priorities may indicatemapping between a logical channel and one or more TTIs/numerologies. Inan example, a priority of a logical channel with a given value (e.g.,zero or minus infinity or a negative value) for a TTI/numerology mayindicate that the logical channel is not mapped to the TTI/numerology.In an example, sizes of the sequence may be variable. In an example, asize of a sequence associated with a logical channel may be a number ofTTIs/numerologies to which the logical channel is mapped. In an example,the sizes of the sequence may be fixed, e.g., the number ofTTIs/numerologies/cells.

In an example, a TTI/numerology for a grant (e.g., as indicated by thegrant/DCI) may not accept data from one or more logical channels. In anexample, the one or more logical channels may not be mapped to theTTI/numerology indicated in the grant. In an example, a logical channelof the one or more logical channels may be configured to be mapped toone or more TTIs/numerologies and the TTI/numerology for the grant maynot be among the one or more TTIs/numerologies. In an example, a logicalchannel of the one or more logical channels may be configured with amax-TTI parameter indicating that the logical channel may not be mappedto a TTI longer than max-TTI, and the grant may be for a TTI longer thanmax-TTI. In an example, a logical channel may be configured with amin-TTI parameter indicating that the logical channel may not be mappedto a TTI shorter than min-TTI, and the grant may be for a TTI shorterthan min-TTI. In an example, a logical channel may not be allowed to betransmitted on a cell and/or one or more numerologies and/or one or morenumerologies of a cell. In an example, a logical channel may containduplicate data and the logical channel may be restricted so that thelogical channel is not mapped to a cell/numerology. In an example, thelogical channel may not be configured with an upper layer configurationparameter laa-allowed and the cell may be an LAA cell.

In an example, a MAC entity and/or a multiplexing and assembly entity ofa MAC entity may perform a logical channel prioritization (LCP)procedure to allocate resources of one or more grants, indicated to awireless device by a base station using one or more DCIs, to one or morelogical channel. In an example, the timing between a grant/DCI receptiontime at the wireless device and transmission time may be dynamicallyindicated to the wireless device (e.g., at least using a parameter inthe grant/DCI). In an example, timing between a grant/DCI reception timeat the wireless device and transmission time may be fixed/preconfiguredand/or semi-statically configured. In an example, the LCP procedure forNR may consider the mapping of a logical channel to one or morenumerologies/TTIs, priorities of a logical channel on the one or morenumerologies/TTIs, the numerology/TTI indicated in a grant, etc. The LCPprocedure may multiplex data from one or more logical channels to form aMAC PDU. The amount of data from a logical channel included in a MAC PDUmay depend on the QoS parameters of a bearer and/or service associatedwith the logical channel, priority of the logical channel on thenumerology/TTI indicated in the grant, etc. In an example, one or moregrants may be processed jointly at a wireless device (e.g., resources ofthe one or more grants are allocated substantially at a same time). Inan example, one or more first grants of the one or more grants may begrouped into a grouped grant with capacity equal to sum of thecapacities of the one or more first grants and the resources of thegrouped grant may be allocated to one or more logical channels.

In an example embodiment, a HARQ feedback timing may be indicated in aDCI scheduling a downlink transmission (e.g., a PDSCH). In an example,DCI may comprise a field with a value/number/integer that indicates thetime between the downlink transmission and HARQ feedback correspondingto the downlink transmission (e.g., ACK or NACK). The HARQ feedback maybe transmitted on a PUCCH and/or PUSCH. In an example, HARQ feedbackcorresponding to a plurality of transport blocks may be transmitted on aPUSCH and/or PUCCH. In an example, the plurality of transport blocks maybe associated with a same numerology/TTI. In an example, at least one ofthe plurality of transport blocks may be associated with anumerology/TTI different from numerologies/TTIs of the other transportblocks in the plurality of transport blocks.

In an example embodiment, a wireless device may monitor a plurality ofPDCCH candidates in a common search space (e.g., in a primary cell) andUE-specific search space (e.g., in secondary cell). In an example, thewireless device may receive a PDCCH/EPDCCH on a first cell schedulingthe wireless device (e.g., for PUSCH and/or PDSCH transmission) on thefirst cell (e.g., self-carrier scheduling). In an example, thePDCCH/EPDCCH received on the first cell may schedule the wireless deviceon a second cell (e.g., cross-carrier scheduling). In an example, forthe cross-carrier scheduling, PDCCH and a scheduled PDSCH may sameand/or different numerologies. In an example, for self-carrierscheduling, a PDCCH and the scheduled PDSCH may have a same or differentnumerology. In an example, for self- and/or cross-carrier scheduling,PDCCH and the scheduled PUSCH may have a same or different numerology.

In an example embodiment, when numerology between PDCCH and thescheduled transmission is different, the time granularity indicated inthe DCI for the timing relationship between the end of the PDCCH and thecorresponding scheduled transmission may be based on the numerology ofthe scheduled transmission.

In an example embodiment, HARQ feedback of a plurality of downlinkcomponent carriers with a same or different numerology may betransmitted together. In an example embodiment, a time granularity ofHARQ feedback transmission indicated in a DCI scheduling a PDSCH may bebased on a numerology of a PUCCH transmission. In an example, the PUCCHmay correspond to the PDSCH (e.g., based on the numerology of PDSCHand/or content of TB(s) in PDSCH and/or service type of TB(s) and/orsize of TB(s) in PDSCH etc.).

In an example, the wireless device may apply one or more offsetparameters for multiplexing of one or more uplink control information(UCI) (e.g., HARQ feedback and/or RI and/or CQI, etc.) in PUSCH. In anexample, the one or more offset parameters may be configured by higherlayers (e.g., RRC configuration). In an example, the one or more offsetparameters may be indicated to the wireless device, e.g., in a DCIscheduling the PUSCH. In an example, the DCI scheduling the PUSCH maycomprise a field, the value of the field indicating the one or moreoffset parameters. In an example, in response to multiplexing one ormore UCI (e.g., HARQ feedback and/or RI and/or CQI, etc.) in the PUSCH,the wireless device may employ the one or more offset parameters todetermine the number of resources and/or resource elements and/or numberof coded modulation symbols and/or coding/coding rate for multiplexingof the one or more UCI in the PUSCH. In an example, in response tomultiplexing one or more UCI (e.g., HARQ feedback and/or RI and/or CQI,etc.) in the PUSCH, the wireless device may employ the one or moreoffset parameters to determine coding parameters, e.g., rates, formultiplexing of the one or more UCI in the PUSCH. In an example, theoffset parameters may be configured and/or indicated as decibel (dB)values. The wireless device may employ the one or more offset parametersto determine resources and/or number of coded modulation symbols and/orcoding and/or block error rate (BLER) requirements etc. of the one ormore UCI and differentiate the one or more UCI from PUSCH. In anexample, RRC may configure a plurality of offset parameters and the DCImay indicate one or more offset parameters in the plurality of offsetparameters.

In an example, UCI may be piggybacked/multiplexed on PUSCH may forDFT-s-OFDM and/or CP-OFDM waveforms. In an example, for all types ofUCI, uplink data may be rate-matched. In an example, for all types ofUCI, uplink data may be punctured. In an example, at least for UCI otherthan HARQ feedback, uplink data may be rate-matched while for HARQ ACK,uplink data may be punctured.

In an example embodiment, PUSCH may be rate-matched around resourceelements carrying HARQ feedback. In an example, to avoid error cases ifthe UE misses some downlink assignments, the uplink grant DCI mayindicate whether to multiplex and/or which UCI to multiplex in thePUSCH. In an example, a wireless device may multiplex HARQ feedbackemploying rate-matching in response to HARQ feedback comprising payloadsmaller than a first threshold and/or TB size being larger than a secondthreshold and/or HARQ feedback payload size in combination with the TBsize satisfying a first condition. The wireless device may multiplexHARQ feedback employing puncturing in response to the HARQ feedbackcomprising a payload larger than the first threshold and/or the TB sizebeing larger than the second threshold and/or the HARQ feedback payloadsize in combination with the TB size not satisfying the first condition.

In an example, a UE may be configured for a single serving cell. The UEmay not be configured for simultaneous PUSCH and PUCCH transmissions. Inan example, the uplink control information (UCI) may be transmitted onPUCCH if the UE is not transmitting PUSCH. In an example, the UCI may betransmitted on PUSCH if the UE is transmitting PUSCH unless the PUSCHtransmission corresponds to a Random Access Response Grant or aretransmission of the same transport block as part of the contentionbased random access procedure, in which case UCI may not be transmitted.

In an example, a UE may be configured for a single serving cell. The UEmay be configured with simultaneous PUSCH and PUCCH transmission. In anexample, UCI may be transmitted on PUCCH. The UE may transmitperiodic/aperiodic CSI on PUSCH unless the PUSCH transmissioncorresponds to a Random Access Response Grant or a retransmission of thesame transport block as part of the contention based random accessprocedure, in which case periodic/aperiodic CSI may not be transmitted.

In an example, a UE may be configured with more than one serving cell.The UE may not be configured for simultaneous PUSCH and PUCCHtransmission. In an example, the UCI may be transmitted on PUCCH if theUE is not transmitting PUSCH. In an example, the UCI may be transmittedon PUSCH of a serving cell given if the UCI consists of aperiodic CSI oraperiodic CSI and HARQ-ACK. In an example, the UI may be transmitted ona primary cell PUSCH if the UCI consists of periodic CSI and/or HARQ-ACKand if the UE is transmitting on the primary cell PUSCH unless theprimary cell PUSCH transmission corresponds to a Random Access ResponseGrant or a retransmission of the same transport block as part of thecontention based random access procedure, in which case UCI may not betransmitted. In an example, the UCI may be transmitted on PUSCH of thesecondary cell with smallest SCellIndex if the UCI consists of periodicCSI and/or HARQ-ACK and if the UE is not transmitting PUSCH on primarycell but is transmitting PUSCH on at least one secondary cell.

In an example, a UE may be configured with more than one serving cell.The UE may be configured with simultaneous PUSCH and PUCCH transmission.In an example, the UCI may be transmitted on PUCCH. In an example, theUCI may be transmitted on PUCCH and primary cell PUSCH if the UCIconsists of HARQ-ACK and periodic CSI and the UE is transmitting PUSCHon the primary cell, in which case the HARQ-ACK may be transmitted onPUCCH and the periodic CSI may be transmitted on PUSCH unless theprimary cell PUSCH transmission corresponds to a Random Access ResponseGrant or a retransmission of the same transport block as part of thecontention based random access procedure, in which case periodic CSI maynot be transmitted. In an example, the UCI may be transmitted on PUCCHand PUSCH of the secondary cell (other than a LAA SCell) with thesmallest SCellIndex if the UCI consists of HARQ-ACK and periodic CSI andif the UE is not transmitting PUSCH on primary cell but is transmittingPUSCH on at least one secondary cell, in which case, the HARQ-ACK may betransmitted on PUCCH and the periodic CSI may be transmitted on PUSCH.In an example, the UCI may be transmitted on PUCCH and PUSCH if the UCIconsists of HARQ-ACK/HARQ-ACK+SR/positive SR and aperiodic CSI in whichcase the HARQ-ACK/HARQ-ACK+SR/positive SR may be transmitted on PUCCHand the aperiodic CSI may be transmitted on PUSCH of a serving cell.

In an example, the MAC entity may be configured with a first parameter(e.g., skipUplinkTxSPS). In an example, an uplink grant received onPDCCH may be addressed to the Semi-Persistent Scheduling C-RNTI. In anexample, the wireless device may ignore an uplink grant in response tothe HARQ buffer for the process associated with the uplink grant beingempty.

In an example, a MAC PDU may include only the MAC CE for padding BSR orperiodic BSR with zero MAC SDUs. In an example, there may be norequested aperiodic CSI. The MAC entity may not generate a MAC PDU forthe HARQ entity in response to the MAC entity being configured withskipUplinkTxDynamic and the grant indicated to the HARQ entity beingaddressed to first RNTI (e.g., C-RNTI). The MAC entity may not generatea MAC PDU for the HARQ entity in response to the MAC entity beingconfigured with skipUplinkTxSPS and the grant indicated to the HARQentity being a configured uplink grant.

In an example, long duration NR-PUCCH for up to 2 bits in a given slotmay comprise HARQ ACK feedback, two-states SR e.g., based on on-offkeying, time domain OCC. In an example, HARQ ACK feedback may betransmitted by BPSK or QPSK modulation and may be repeated in timedomain and multiplied with sequence(s).

In an example, NR may support one long PUCCH format for UCI with up to 2bits with high multiplexing capacity. In an example, NR may support onelong PUCCH format for UCI with large payload with no multiplexingcapacity. In an example, NR may support one long PUCCH format for UCIwith moderate payload with some multiplexing capacity.

In an example, at least a first PUCCH with a short duration and/or asecond PUCCH with a long duration may be configured for a wirelessdevice. The first PUCCH and the second PUCCH may be transmitted ondifferent numerologies/TTIIs. In an example, the short PUCCH may employa numerology with a shorter TTI than the long PUCCH. In an example,there may be a mapping between a type of uplink control information(UCI) and the type of PUCCH (e.g., short PUCCH or long PUCCH) thatcarriers the UCI. In an example, periodic CSI may be reported at leaston short PUCCH or long PUCCH. In an example, the periodic CSI may bereported in a single slot. In an example, the periodic CSI may bereported us single slot and/or multiple slots. In an example, type I CSIfeedback may be reported for P/SP/A-CSI. In an example, type I CSIfeedback may be carrier on either PUCCH or PUSCH. In an example, type ICSI feedback may be carrier on either one of PUSCH or long PUCCH. In anexample, type II CSI feedback may be carrier at least on PUSCH.

In an example, for a long PUCCH with up to 2 bits UCI, DMRS may occur inevery symbol in long PUCCH. In an example, for a long PUCCH with up to 2bits UCI, DMRS may occur in even and/or odd symbols in long PUCCH. In anexample, for a PUCCH format for UCI with large payload and/or with nomultiplexing capacity within a slot: the DMRS and UCI may be mapped todifferent symbols. In an example, for intra-slot frequency-hopping, oneor two DMRS symbol(s) may be mapped on each frequency-hop of thelong-PUCCH. In an example, there may be one DMRS per frequency-hop. Thelocation may be around the middle of the frequency-hop. In an example,there may be one or two DMRS per frequency-hop.

In an example, a logical channel prioritization procedure in a MAC layerof a wireless device may take into account a plurality ofinformation/parameters indicated by an uplink grant DCI for itsmultiplexing functionalities and creating transport blocks. In anexample, at least part of the information/parameters indicated by theDCI/profile may be visible to the MAC layer and/or logical channelprioritization procedure. The plurality of information may be indicatedto the wireless device explicitly or implicitly. In an example, RRC mayconfigure the wireless device with a plurality of profiles and theuplink grant DCI may indicate an index to a profile in the plurality ofprofiles. In an example, the uplink grant DCI may comprise a fieldindicating the index. The profile may comprise a plurality of parameterscomprising a numerology (e.g., numerology to be employed fortransmission of PUSCH) and/or TTI (e.g., TTI to be employed fortransmission of PUSCH) and/or a QoS profile for example indicating aservice type associated with the grant/PUSCH and/or logical channelsassociated with the grant/PUSCH and/or power-related parameters (e.g.,power headroom reporting, etc.) and/or one or more restrictions that thewireless device may consider when multiplexing data (e.g., MAC SDUsand/or MAC CEs) in at least one TB associated with the grant/PUSCH.

In an example, a DCI scheduling a transmission in downlink, uplink,etc., may indicate numerology/TTI corresponding to the scheduledtransmission. In an example, a DCI indicating a downlink assignment mayindicate a cell/numerology/TTI corresponding to the scheduled downlinkassignment. In an example, the numerology/TTI may be implicitlyindicated. For example, the wireless device may implicitly determine anumerology/TTI corresponding to a scheduled transmission from thenumerology/TTI on which the DCI is received. In an example, thenumerology/TTI may be implicitly indicated by the DCI by indicating aprofile/index. The wireless device may be configured with a plurality ofprofiles and the index indicated by the DCI may determine the profile.In an example, the profile may comprise a plurality of parameterscomprising the numerology/TTI. In an example, the DCI may comprise afield, the value of the field indicating the profile (e.g., using anindex). In an example, the numerology/TTI of the scheduled transmissionmay be explicitly indicated, e.g., in the scheduling DCI. In an example,the scheduling DCI may comprise a field indicating the numerology/TTI ofthe scheduled transmission.

In an example, the DCI scheduling a transmission may indicate a timingbetween the DCI and the scheduled transmission (e.g., timing between DCIand PUSCH or timing between DCI and PDSCH, etc.). In an example, thetiming may be explicitly indicated in the DCI. In an example, the timingmay be indicated as a number (e.g., integer). In an example, thescheduling DCI may comprise a field, the value of the field may indicatethe timing. In an example, the timing may be implicitly indicated to thewireless device by the DCI. In an example, the base station mayconfigure the wireless device with a plurality of timing values and theDCI may indicate one of the plurality of the configured timing values.In an example, the wireless device may use the value of timing indicatedin the DCI along with a timing granularity to determine the time betweenthe DCI and the scheduled transmission. The timing granularity may bebased on a rule. In an example, the timing granularity between a DCI anda scheduled PUSCH may be based on a numerology of the PUSCH (e.g., interms of OFSM symbols, TTI, slot, etc.). In an example, the timinggranularity between DCI and the PDSCH may be based on the numerology ofthe PDSCH. In an example, in case of self-carrier scheduling PDSCH, thePDCCH and the PDSCH may have a same numerology. The wireless device mayimplicitly determine that the time granularity between DCI and the PDSCHis based on the numerology of the PDCCH/DCI.

In an example embodiment, the wireless device may transmit HARQ feedbackassociated with a PDSCH on a PUCCH and/or multiplex the HARQ feedbackassociate with a PDSCH on a PUSCH. The timing between the PDSCH and theHARQ feedback may be indicated in the DCI. In an example, the timing maybe explicitly indicated to the wireless device. In an example, thetiming may be implicitly indicated to the wireless device. The basestation may configure (e.g., with RRC) a plurality of timing values andthe DCI may indicate a timing value among the plurality of timingvalues. In an example, the DCI may comprise a field indicating thetiming between scheduled PDSCH and the HARQ feedback associated with thescheduled PDSCH. In an example, a DCI format may not comprise a HARQfeedback timing field. The wireless device may not transmit HARQfeedback for scheduled downlink transmission associated with the DCI.The wireless device may determine the time between PDSCH and HARQfeedback based on the timing indicated by the DCI and a timinggranularity. In an example, the wireless device may determine the timinggranularity between PDSCH and HARQ feedback based on numerology of aPUCCH associated with the PDSCH.

In an example, a wireless device may be configured with a plurality ofcell groups. In an example, a cell group in the plurality of cell groupsmay be associated with one or more PUCCHs, e.g., one or more carrierstransmitting PUCCH. In an example, the one or more PUCCHs within a cellgroup may have a same numerology/TTI. In an example, at least two of theone or more PUCCHs within a cell group may have differentnumerologies/TTIs. In an example, a PDSCH and/or TTI/numerologyassociated with a PDSCH transmitted on a cell in a cell group may beassociated with a PUCCH in the cell group e.g., based on thenumerology/TTI associated with the PDSCH, the TB(s) content/size/servicetype associated with the PDSCH, etc. The wireless device may determinetiming between the PDSCH and HARQ feedback for the PDSCH based on anumerology corresponding to the PUCCH associated with PDSCH.

In an example, a wireless device may be configured with periodicresource allocation. The periodic resource allocation may comprisesemi-persistent scheduling (SPS) and/or grant-free (GF) resourceallocation. In an example, the configuration parameters for SPS and/orGF may comprise an interval and/or MCS and/or one or more power controlparameters and/or an implicit release parameter and/or other parametersfor identifying an allocated resources, etc. In an example SPS and/or GFmay be activated for the wireless device in response to receiving anactivation DCI. In an example, the SPS and/or GF resources may bereleased in response to receiving a release DCI. In an example, the SPSand/or GF resource may be implicitly released in response to notutilizing an allocated resource for a first number of times, e.g., basedon the implicit release parameter. In an example, the RRC configurationof GF may activate associated resources for the GF. The wireless devicemay employ the parameters in an activating DCI and/or RRC parameters toidentify allocated resource for SPS and/or GF and/or generate transportblocks for transmission employing the allocated resources.

In legacy procedures for UCI multiplexing in PUSCH, the wireless devicemay multiplex one or more UCI in a PUSCH without considering physicallayer attributes and/or service type and/or content (e.g., logicalchannels included in TB(s)) of the PUSCH (except in some scenarios wherethe wireless device may not multiplex PUSCH in an LAA cell). With theincrease in UCI feedback (e.g., increase in HARQ feedback due to codeblock group based HARQ feedback, etc.), the TB(s) transmitted in PUSCHmay be subject to higher levels of error due to UCI multiplexing. Thereis a need to enhance the UCI multiplexing process to improve theefficiency of uplink transmission in case a high payload of UCI ismultiplexed in a PUSCH. Example embodiment enhance the legacy UCI and/orHARQ feedback multiplexing processes. Some of the feature of the exampleembodiments may be combined to improve the efficiency in uplinktransmission.

In an example, the HARQ process ID for the at least one TB may bederived by the wireless device for example based on the uplink resourcesfor transmission of the at least one TB. In an example, DCI may indicatea transmission timing for the at least one TB. In an example, the timegranularity for determining the time between the DCI and the PUSCH maybe based on the numerology pf the PUSCH. In an example, the parametersindicated in the DCI for transmission of the at least one TB maycomprise a profile and/or index. In an example, RRC may configure aplurality of profiles for the wireless device. A profile in theplurality of profiles may comprise a numerology and/or TTI and/or one ormore power-related parameters and/or service type of the at least one TBand/or one or more logical channels that may be included in the at leastone TB and/or other parameters. In an example, the DCI for transmissionof the at least one TB may indicate an index to a first profile in theplurality of profiles. At least some of the parameters indicated by thefirst profile may be visible to the MAC layer. For example, a firstnumerology and/or a first TTI and/or a first service type and/or thelogical channels for including in the at least one TB that are indicatedby the first profile may be visible to the MAC layer. In an example, thefirst profile index may be visible to the MAC layer and the parametersin the first profile may be known by the MAC layer by knowing the firstprofile index.

In an example, the one or more criteriamay comprise the first PUSCH being transmitted on a secondary cell withsmallest cell index. In an example, the one or more criteria maycomprise the first PUSCH being transmitted on a smallest cell index thatis not a licensed assisted access (LAA) cell. In an example embodiment,the one or more criteria may comprise considering and/or may be based onthe first profile indicated by the DCI for transmission of the at leastone TB in the first PUSCH.

In an example embodiment, the one or more UCI may betransmitted/multiplexed on the first PUSCH in response to the firstprofile not being one of one or more profiles. In an example, the one ormore profiles may be configured for the wireless device (e.g., with RRCconfiguration). In an example, the one or more profiles may bepre-configured profiles.

In an example, the one or more service types and/orlogical channels may be configured for the wireless device (e.g., withRRC configuration). In an example, the one or more service types and/orlogical channels may be pre-configured service types. In an example, theone or more service types and/or logical channels may be indicated tothe wireless device (e.g., by a DCI, etc.).

In an example embodiment, an uplink grant DCI scheduling a PUSCH, maycomprise a field indicating whether the wireless device may multiplexone or more UCI in the PUSCH corresponding to the uplink grant. In anexample, the uplink grant DCI may indicate whether the wireless devicemay multiplex one or more UCIs among a plurality of UCI in the PUSCHand/or whether the wireless device may not multiplex one or more secondUCIs among a plurality of UCIs in the PUSCH. For example, the uplinkgrant may indicate that the wireless device may multiplex CSI in thePUSCH and may not multiplex HARQ feedback in the PUSCH. The wirelessdevice may consider this indication when multiplexing UCI on the PUSCH.For example, the wireless device may multiplex one or more UCI in thePUSCH with smallest cell index that its corresponding DCI indicates thatthe one or more UCI may be multiplexed in the PUSCH and/or itscorresponding DCI does not indicate that the one or more UCI may not bemultiplexed in the PUSCH. In an example, wireless device may considerthe indication in an uplink grant corresponding to a DCI along withother restrictions/rules (e.g., being the smallest cell index, not beingan LAA cell, etc.) when deciding whether to multiplex UCI in a PUSCH.

In an example embodiment, a wireless device may employ a methodcomprising receiving a DCI indicating parameters for transmitting atleast one transport block on a first PUSCH.

In an example, the wireless device may transmit/multiplex one ormore UCI on the first PUSCH or a second PUSCH or a PUCCH at least basedon the profile and/or the first TTI/numerology. In an example, thewireless device may not multiplex the one or more UCI in the first PUSCHin response to the first TTI/numerology being one of the one or moreconfigured (e.g., RRC configured) and/or pre-configuredTTIs/numerologies. In an example, one or more pre-configured and/orconfigured (e.g., RRC configured) service types may be mappable to theone or more configured/pre-configured TTIs/numerologies. In an example,the one or more UCI may comprise HARQ feedback.

In an example, DCI may indicate a transmission timingfor the at least one TB. In an example, the time granularity fordetermining the time between the DCI and the PUSCH may be based on thenumerology pf the PUSCH. In an example, the parameters indicated in theDCI for transmission of the at least one TB may comprise a profileand/or index. In an example, RRC may configure a plurality of profilesfor the wireless device. A profile in the plurality of profiles maycomprise a numerology and/or TTI and/or one or more power-relatedparameters and/or service type of the at least one TB and/or one or morelogical channels that may be included in the at least one TB and/orother parameters. In an example, the DCI for transmission of the atleast one TB may indicate an index to a first profile in the pluralityof profiles. At least some of the parameters indicated by the firstprofile may be visible to the MAC layer. For example, a first numerologyand/or a first TTI and/or a first service type and/or the logicalchannels for including in the at least one TB that are indicated by thefirst profile may be visible to the MAC layer.

Thewireless device may skip an uplink grant even if the wireless device hasone or more UCI (e.g., HARQ feedback) to transmit. With the base stationindicating to a wireless device to transmit/multiplex one or more UCI(e.g., HARQ feedback), the legacy procedure for skipping may lead toinefficient performance.

In an example, DCI may indicate a transmission timingfor the at least one TB. In an example, the time granularity fordetermining the time between the DCI and the PUSCH may be based on thenumerology of the PUSCH. In an example, the parameters indicated in theDCI for transmission of the at least one TB may comprise a profileand/or index. In an example, RRC may configure a plurality of profilesfor the wireless device. A profile in the plurality of profiles maycomprise a numerology and/or TTI and/or one or more power-relatedparameters and/or service type of the at least one TB and/or one or morelogical channels that may be included in the at least one TB and/orother parameters. In an example, the DCI for transmission of the atleast one TB may indicate an index to a first profile in the pluralityof profiles. At least some of the parameters indicated by the firstprofile may be visible to the MAC layer. For example, a first numerologyand/or a first TTI and/or a first service type and/or the logicalchannels for including in the at least one TB that are indicated by thefirst profile may be visible to the MAC layer.

In an example, the wireless device may transmit the at least oneTB on a PUSCH with numerology and/or TTI and/or considering otherparameters indicated in the DCI and/or the first profile.

In an example embodiment, a multiplexing and assembly entity in thewireless device may ignore the skipping parameter and may create a MACPDU in response to the DCI scheduling the first PUSCH indicating one ormore first parameters for multiplexing one or more HARQ feedback in thefirst PUSCH. In an example, the one or more first parameters in the DCImay nay indicate resources for transmission of HARQ feedback. In anexample, the one or more first parameters may indicate one or moresecond parameters for multiplexing one or more UCI (e.g., HARQ feedback)in the first PUSCH. In an example, the one or more second parameters maybe employed by the wireless device for determining the resources formultiplexing one or more UCI (e.g., HARQ feedback) in the first PUSCH.In an example, the one or more second parameters may be employed by thewireless device to determine a number of coded modulation symbols and/ora coding rate corresponding to the one or more UCI (e.g., HARQfeedback).

In an example embodiment, a wireless device may employ a methodcomprising receiving one or more messages comprising configurationparameters. In an example, the configuration parameters may comprise askipping parameter. In an example, the wireless device may receive a DCIcomprising transmission parameters for at least one TB on a PUSCH. In anexample, the wireless device may ignore the skipping parameter inresponse to the DCI comprising one or more first parameters formultiplexing one or more HARQ feedback in the PUSCH. In an example, inresponse to having no data to transmit, the wireless device maydetermine whether to skip an uplink grant based on a parameter indicatedby the RRC (e.g., the skipping parameter) and one or more parametersindicated by a DCI (e.g., the DCI indicating the uplink grant). In anexample, the wireless device may transmit the at least TB. In anexample, the skipping parameter may indicate skipping generating a MACPDCU in response to the wireless device having no data to transmit. Inan example, the one or more first parameters may indicate resources fortransmission of HARQ feedback. In an example, the one or more firstparameters may be employed by the wireless device to determine resourcesfor UCI multiplexing in the PUSCH. In an example, the one or more firstparameters may be employed by the wireless device to determine a numberof coded modulation symbols and/or coding rate for the UCI.

In an example, a wireless device may multiplex uplink controlinformation (UCI) in an uplink data channel and may transmit the UCIwith a transport block. In an example, a wireless device may transmitUCI via uplink control channel. The number of resources for transmissionof the uplink control information via the uplink data channel aredetermined based on one or more offset parameters. When the UCI ismultiplexed in the uplink data channel and transmitted with a transportblock, it may have some impact on decoding performance of the transportblock at the base station depending on the number of resources. Forexample, if a number of resources of the UCI is large, it may increasedecoding error of the transport block at the base station.

A base station my assign uplink radio resources to one or more wirelessdevices using dynamic grants or configured grants (periodic resourceallocation). In the legacy procedures, a base station transmits to awireless device the one or more offset parameters using the samemechanism for both dynamic grants and configured grants. For example, abase station may transmit one or more RRC messages comprising the one ormore offset parameters that semi-statically configures the one or moreoffset values for dynamic and configured grants. For example, a basestation may transmit one or more downlink control information (physicallayer signals) comprising the one or more offset parameters thatdynamically configures the one or more offset values for dynamic andconfigured grants. Implementation of legacy mechanism may reduce uplinksignaling overhead and increase uplink decoding error rates when dynamicand configured grants are implemented. There is a need to enhanceexisting mechanisms for configuration of a number of UCI resources inthe uplink data channel and enhance UCI multiplexing in the uplink whendynamic and configured grants are implemented. Example embodimentsimplement different signaling mechanisms for dynamic grants andconfigured grants to indicate the one or more offset values. Exampleembodiments may increase downlink signaling overhead, however exampleembodiment may decrease uplink decoding errors and therefore increaseoverall air interface spectral efficiency. Example embodiments implementenhanced signaling mechanisms between a base station and a wirelessdevice to improve uplink spectral efficiency and reduce decoding errorrates when dynamic and configured grants are implemented.

In an example embodiment and as shown in FIG. 20, a wireless device mayreceive one or more messages comprising: configuration parameters for aperiodic resource allocation indicating a first plurality of uplinkresources of an uplink data channel of a cell; and one or more offsetparameters for determining a number of uplink control information (UCI)resources. The wireless device may receive a downlink controlinformation comprising: an uplink grant indicating uplink radioresources of the uplink data channel of the cell; and an offsetindicator value. The wireless device may transmit a first transportblock and one or more first UCI via the uplink radio resources of theuplink data channel of the cell, wherein: the uplink radio resourcescomprise first resources of the one or more first UCI; and a firstnumber of the first resources are determined based on the offsetindicator value. The wireless device may transmit a second transportblock and one or more second UCI via one of the first plurality ofuplink resources of the uplink data channel of the cell, wherein: theone of the first plurality of uplink resources comprise second resourcesof the one or more second UCI; and a second number of the secondresources are determined based on the one or more offset parameters.

In an example, the one or more first UCI may comprise one or more firsthybrid automatic repeat request (HARQ) feedback information. In anexample, the one or more second UCI may comprise one or more second HARQfeedback information. In an example, the one or more first HARQ feedbackmay be for one or more first downlink transmissions. In an example, theone or more second HARQ feedback may be for one or more second downlinktransmissions. In an example, the one or more first downlinktransmissions may correspond to one or more first downlink controlinformation. In an example, the first transport block may be transmittedin a first slot. In an example, one or more first parameters in the oneor more first downlink control information may indicate transmission ofthe one or more first HARQ feedback in the first slot.

In an example, the configuration parameters of the periodic resourceallocation may comprise a periodicity parameter. The first plurality ofuplink radio resources may be determined based on the periodicity. In anexample, the one or more first UCI or the one or more second UCI may bemultiplexed in the uplink data channel. In an example, the firstplurality of uplink radio resources may correspond to a plurality ofconfigured grants. In an example, the downlink control information mayindicate a numerology of the uplink data channel. In an example, the oneor more first UCI may be multiplexed in the uplink data channel by ratematching the uplink data channel. In an example, the one or more firstUCI may be multiplexed in the uplink data channel by puncturing theuplink data channel. In an example, the one or more second UCI aremultiplexed in the uplink data channel by rate matching the uplink datachannel. In an example, the one or more second UCI may be multiplexed inthe uplink data channel by puncturing the uplink data channel. In anexample, the first transport block comprises data from one or morelogical channels may be based on a numerology of the uplink datachannel.

The skipping procedure enables a wireless device to ignore an uplinkgrant when the wireless device has not data to transmit. In legacyprocesses, the wireless may not multiplex UCI in the uplink data channelwhen an uplink grant is skipped due to lack of data at the wireless fortransmission based on the uplink grant. The base station may, using aDCI comprising an uplink grant, dynamically indicate one or more offsetto the wireless device to multiplex UCI based on the one or more offsetparameters. The UCI (for example comprising HARQ feedback, CSI, etc.)may be critical for network performance and skipping transmission of theUCI may lead to performance degradation including throughput loss andincreased latency. Example embodiments enhance the UCI multiplexingprocesses when a wireless device is configured with skipping.

In an example embodiment and as shown in FIG. 21, a wireless device mayreceive one or more messages comprising configuration parameterscomprising a skipping parameter. The wireless device may receive adownlink control information indicating: transmission parameters fortransmission of a transport block via an uplink data channel and anoffset indicator value for determining a number of resources of one ormore uplink control information in the uplink data channel. The wirelessdevice may ignore the skipping parameter when the wireless device has nodata for the transport block in response to the downlink controlinformation comprising the offset indicator value. The wireless devicemay transmit the one or more uplink control information via the uplinkdata channel. In an example, the skipping parameter may indicateskipping the transmission of the transport block when the wirelessdevice has no data for the transport block. In an example, the one ormore uplink control information may comprise one or more hybridautomatic repeat request feedback information. In an example, theignoring the skipping parameter may comprise creating a medium accesscontrol packet. In an example, the one or more uplink controlinformation may be transmitted by puncturing the uplink data channel. Inan example, the one or more uplink control information may betransmitted by rate matching the uplink data channel. In an example, theone or more uplink control information may be multiplexed in the uplinkdata channel based on a multiplexing process based on a size of theuplink control information. In an example, the transmission parametersindicate uplink radio resources for the transmission of the transportblock. In an example, the downlink control information indicates anumerology of the uplink data channel. The wireless device may have nodata in logical channels that can be transmitted via a transmissionduration corresponding to the numerology. In an example, the one or moreuplink control information may comprise one or more channel stateinformation. In an example, a transmission time of the transport blockis based on the numerology of the uplink data channel.

The uplink control information (UCI) may be multiplexed in uplink datachannel and transmitted with a transport block or the UCI transmittedvia uplink control channel. When the UCI is multiplexed in the uplinkdata channel and transmitted with a transport block, it has impact onthe decoding performance of the transport block at the base station. Forexample, if the number of resources of the UCI is large, it may increasethe decoding error of the transport block at the base station. Thelegacy procedures for multiplexing uplink control information do notconsider the data content of and/or logical channels multiplexed in thetransport block. The legacy procedures also do not consider thenumerology/TTI duration corresponding to the uplink data channel or thesize of transport block when multiplexing UCI. The transport block maycomprise data from logical channels that are QoS sensitive (e.g.,ultra-reliable low-latency communication (URLLC) data). The transportblock may be transmitted via an uplink data channel that corresponds toa numerology/TTI duration that is used for transmission of QoSsensitive. Also, the size of the transport block may be such that themultiplexed UCI leads to increased decoding error of transport blocks.The legacy procedures lead to increased decoding error performance ofthe transport blocks at the base station leading to degraded networkperformance including throughput loss or increased latency. Exampleembodiments enhance the UCI multiplexing process.

In an example embodiment and as shown in FIG. 24, a wireless device mayreceive one or more messages comprising configuration parameters of oneor more logical channels. The wireless device may select a multiplexingprocess for transmitting uplink control information via an uplinkchannel employed for transmission of a transport block, wherein: thetransport block comprises data of the one or more logical channels; andthe selecting is based on the configuration parameters of the one ormore logical channels. In an example, the wireless device may multiplexthe uplink control information in the uplink channel employing themultiplexing process. The wireless device may transmit the transportblock and the uplink control information via the uplink channel. In anexample, the one or more logical channels may correspond to one or moreservice types. In an example, the one or more service types may compriseultra-reliable low-latency communications.

In an example, the multiplexingprocess is selected from a plurality of multiplexing processescomprising: a rate matching of the uplink channel and a puncturing ofthe uplink channel. In an example, the configuration parameters of theone or more logical channels may indicate one or more first transmissiondurations; and data of the one or more logical channels may betransmitted employing uplink grants that result in a transmissionduration shorter than or equal to the one or more first transmissiondurations.

Thewireless device may select, based on the first numerology, amultiplexing process for transmitting uplink control information via theuplink data channel employed for transmission of the transport block.The wireless device may multiplex the uplink control information in theuplink data channel employing the multiplexing process. In an example,the multiplexing process may be based on a first transmission timeinterval corresponding to the first numerology. In an example, themultiplexing process may be based on one or more logical channels thatcan be transmitted employing uplink grants that result in a transmissionduration that is smaller than or equal to the first transmissionduration. In an example, the multiplexing process may be based onwhether the one or more logical channels correspond to a first servicetype. In an example, the first service type may be ultra-reliablelow-latency communications. In an example, the multiplexing process isselected from a plurality of multiplexing processes comprising: a ratematching of the uplink data channel and a puncturing of the uplink datachannel. In an example, the wireless device may receive configurationparameters of a plurality of logical channels, wherein the transportblock comprises data of one or more logical channels in the plurality oflogical channels based on the first numerology.

Inan example, the one or more logical channels may correspond to one ormore service types comprising ultra-reliable low-latency communications.In an example, the uplink control information comprise hybrid automaticrepeat request feedback. In an example, the determining may be based onwhether the one or more logical channels comprise one or more firstlogical channels.

In an example embodiment and as shown in FIG. 27, the wireless devicemay receive a downlink control information for transmission of atransport block via an uplink data channel, wherein the downlink controlinformation indicates a first numerology of the uplink data channel. Thewireless device may determine to multiplex uplink control information inthe uplink data channel based on the first numerology. The wirelessdevice may transmit the uplink control information via the uplink datachannel based on the determining. In an example, the determining may bebased on a first transmission time interval corresponding to the firstnumerology. In an example, the determining may be based on one or morelogical channels that can be transmitted employing uplink grants thatresult in a transmission duration that is smaller than or equal to thefirst transmission duration. In an example, the determining may be basedon whether the one or more logical channels correspond to a firstservice type. In an example, the first service type is ultra-reliablelow-latency communications.

In an example embodiment and as shown in FIG. 28, a wireless device mayreceive a downlink control information comprising transmissionparameters for a transport block of a first size for transmission via afirst uplink channel. The wireless device may determine to multiplex afirst portion of uplink control information in the first uplink channelbased on the first size. The wireless device may transmit the firstportion of the uplink control information via the first uplink channelbased on the determining. The wireless device may transmit a secondportion of the uplink control information via a second uplink channel.In an example, the second uplink channel is an uplink control channel.In an example, the second uplink channel is an uplink data channel. Inan example, the first portion of the uplink control information ismultiplexed in the first uplink channel by one of a plurality ofmultiplexing processes comprising: puncturing the first uplink channeland rate matching the first uplink channel. In an example, the wirelessdevice may receive one or more configuration parameters indicatingsimultaneous transmission on the first uplink channel and the seconduplink channel. In an example, the second portion of the uplink controlinformation may be a remaining portion of the uplink controlinformation. In an example, the downlink control information mayindicate a numerology of the first uplink channel and the transportblock comprises data of one or more logical channels based onconfiguration parameters of the one or more logical channels and thenumerology. In an example, the downlink control information indicates atime domain resource assignment and a transmission time of the transportblock is based on the time domain resource assignment and a numerologyof the first uplink channel. In an example, the transmission parametersindicate uplink radio resources for transmission of the transport block.In an example, the uplink control information may comprise hybridautomatic repeat request feedback information.

In an example, downlink assignments transmitted on the PDCCH/EPDCCH mayindicate if there is a transmission on a DL-SCH for a particular MACentity and provide the relevant HARQ information. In an example, the MACentity may be configured with a C-RNTI and/or Semi-Persistent SchedulingC-RNTI and/or or Temporary C-RNTI. The MAC entity may monitor PDCCH fora Serving Cell to detect PDCCH candidates associated with its configuredRNTIs. In an example there may be one HARQ entity at the MAC entity fora Serving Cell which maintains a number of parallel HARQ processes. AHARQ process may be associated with a HARQ process identifier. The HARQentity may direct HARQ information and associated TBs received on theDL-SCH to the corresponding HARQ processes.

In an example, to transmit on the UL-SCH, the MAC entity may need avalid uplink grant. The MAC entity may receive the uplink grantdynamically on the PDCCH or in a Random Access Response or the uplinkgrant may be configured semi-persistently or preallocated by RRC. In anexample, the MAC layer may receive HARQ information from lower layers.When the physical layer is configured for uplink spatial multiplexing,the MAC layer may receive at least two grants from lower layers. In anexample, there may be one HARQ entity at the MAC entity for a servingcell with configured uplink. The HARQ entity for the serving cell maymaintain a number of parallel HARQ processes allowing transmissions totake place continuously while waiting for the HARQ feedback on thesuccessful or unsuccessful reception of previous transmissions.

In an example, for cross-carrier scheduling for carriers with differentnumerology, there may be an impact on minimum HARQ RTT timing. In anexample, the impact may be related to the timing relationship includingDCI-to-data and data-to-ACK timing. In an example, if the gNB and UEprocessing timing is not changed, the minimum HARQ RTT timing may beincreased in response to numerology of PDCCH/DCI and/or HARQ-ACK (e.g.,in PUCCH or PUSCH) being different from numerology of data (e.g., PDSCHor PUSCH). In an example, the HARQ RTT may increase in response to slotduration of DCI/HARQ-ACK being larger than the slot duration of data. Anexample scenario is shown in FIG. 19 wherein the HARQ RTT time incross-carrier scheduling is larger than the self-carrier scheduling.Consequently, the wireless device may be scheduled with a maximum numberof HARQ processes while the RTT corresponding to a first scheduled HARQprocess and/or all of the scheduled HARQ processes may not be elapsedyet (or a corresponding HARQ RTT timer(s) may be running). The wirelessdevice may not be scheduled with a new uplink/downlink transmission ifat least one of the RTTs corresponding to one of the HARQ processeselapses (e.g., the corresponding HARQ RTT timer stops). The legacyprocedure for monitoring PDCCH candidates monitoring may lead toincreased battery power consumption by the wireless device. There is aneed to enhance wireless device PDCCH monitoring process when HARQ RTTis larger than a maximum number of HARQ processes in response todifferences in numerologies of scheduling PDCCH and scheduledPDSCH/PUSCH.

The numerology of a scheduling cell/bandwidth part and a scheduledcell/bandwidth part (e.g., for both uplink or downlink scheduling) maybe different. Due to the differences in numerologies and subcarrierspacings, the slot lengths/symbol durations of the schedulingcell/bandwidth part and the scheduled cell/bandwidth part can bedifferent. It is possible that all of HARQ processes are scheduled andtheir corresponding HARQ RTT timer are simultaneously running. Thelegacy procedures require the wireless device to continue monitoring thecontrol channel even if all of the HARQ processes are currentlyscheduled. This leads to increased battery power consumption. Exampleembodiments enhance the control channel monitoring processes.

Theplurality of cells may comprise a primary cell and one/or more secondarycells. The plurality of cells may comprise a first cell.

In an example, the first number ofHARQ processes may be maximum number of HARQ processes in downlink. Inan example, the one or more messages may comprise a second HARQ processnumber. In an example, the second HARQ process number may be maximumnumber of HARQ processes in uplink.

In anexample, the one or more first RNTI may comprise a C-RNTI. The one ormore first RNTI may comprise one or more other RNTIs.
